The checklist
Process identity
- Wall/segment and current approved print-file revision match the active production run.
- Material batch and required printer/process monitoring records are traceable to this visit.
Extrusion and geometry
- Extrusion is continuous without unacceptable gaps, under-extrusion or over-extrusion.
- Measured bead width and layer height meet approved tolerances at required sampling locations.
- Layer alignment and contact are within the approved geometry requirements.
- Wall position and developing geometry remain within approved setting-out tolerances.
Buildability and system control
- No progressive slumping, bulging, leaning or loss of stability is observed.
- Nozzle clearance is appropriate; no unacceptable drag, collision or deposited-layer disturbance is observed.
- Layer intervals and material age remain within the qualified process window.
- Process/environmental parameters remain within the approved operating range.
Interfaces and defects
- Required reinforcement/embedded items installed during this visit are checked before concealment under the applicable ITP.
- Visible defects or deviations are identified, located, recorded and escalated under the project procedure.
Visit disposition
- Any failed critical condition has led to the required hold, notification or engineering disposition before proceeding.

At a glance
- For a single quality surveillance visit while a specific wall/segment is being printed.
- Observe extrusion, bead/layer geometry, layer contact, print stability, process timing and embedded items.
- No generic numeric limits: use the approved qualified process and project acceptance criteria.
